Light Requirements:
Lycopodium obscurum L. var. isophyllum Hickey typically grows in shaded or partially shaded areas. Very little direct sunlight can be tolerated as it can cause leaf scorching and dehydration. It is recommended to place the plant in a location that receives indirect sunlight or under a canopy of trees where the foliage can benefit from dappled sunlight.
Temperature Requirements:
The growth of Lycopodium obscurum L. var. isophyllum Hickey is dependent on temperature, and it thrives in cool conditions. The optimal temperature range for growth is 50°F to 70°F. However, temperatures above 80°F may cause the plant to wither, so it must be kept in a cool and shaded location. During winter, it can tolerate sub-freezing temperatures, but excessive cold can damage the foliage.
Soil Requirements:
Lycopodium obscurum L. var. isophyllum Hickey prefers well-drained, rich soils that are slightly acidic. The pH range for the growth of the plant is 4.5 to 6.0. The soil must have good water retention capacity as the plant requires consistent moisture levels to flourish. The addition of organic matter to the soil can help improve the nutrient content and water-holding capacity. It is recommended to avoid heavy compacted soils or soils with high clay content.
Cultivation Methods
Lycopodium obscurum L. var. isophyllum Hickey, commonly referred to as ground pine or firmoss, is a type of evergreen fern that thrives in shaded areas and moist soil conditions. It's a perfect addition to outdoor gardens or indoor plant collections as it offers distinct foliage and unique texture.
The plant can be propagated from spores, which can be collected from mature plants or purchased from a reputable supplier. Propagation by division can also be performed, ideally during the growing season when the plant has active growth. It's important to choose a well-draining soil mixture when planting the fern and to keep the soil consistently moist without overwatering.
Watering Needs
The Lycopodium obscurum L. var. isophyllum Hickey is quite tolerant of damp conditions, and therefore, it requires consistent watering. You must keep the soil slightly moist at all times, but avoid waterlogging the soil, as this can lead to root rot. During warm weather or extended periods without rain, water the plant in the morning or evening, allowing the soil to soak up water but without overflowing the pot. During colder weather or dormant periods, reduce watering, but keep the soil slightly moist to avoid extreme dehydration.
Fertilization
The fern thrives in moist soil and rarely requires fertilizer. However, should you feel the need to fertilize, use a water-soluble balanced NPK fertilizer with equal parts of nitrogen, phosphorous, and potassium. Dilute the fertilizer to half strength and apply every six to eight weeks. It's important to avoid over-fertilizing, as this can lead to an imbalance in soil pH and cause damage to the fern.
Pruning
The firmoss plant typically doesn't require pruning as it grows slowly. However, if you notice dead or diseased foliage, remove it to prevent it from spreading to other parts of the plant or other plants in your garden. Use a clean, sharp gardening tool, and make clean cuts. Additionally, if the fern outgrows its container, repot it to a larger container during spring or summer by removing it from the old container, loosening any bound up clusters of roots, and replanting in fresh soil.
Propagation of Lycopodium Obscurum L. Var. Isophyllum Hickey
Lycopodium Obscurum L. Var. Isophyllum Hickey, commonly known as ground pine or running pine, is a herbaceous evergreen plant native to North America. It is often found in moist woodlands and open areas, and it is commonly grown as an ornamental plant due to its fern-like foliage. Propagation of L. obscurum var. isophyllum may be performed using several methods, including spore propagation, division, and stem cuttings.
Spore Propagation
Propagation via spores can be challenging, but it is the most natural way to propagate Lycopodium obscurum var. isophyllum. Spores are small and dust-like, and they are usually found on the underside of the fronds. To successfully grow L. obscurum var. isophyllum from spores, one needs to collect the spores in late summer/early fall from mature fronds.
Ensure that the spores are sown on a sterilized soil mix with the correct moisture and temperature. It will take time for the spores to germinate and take root, so patience is essential. Keeping the soil mix moist and warm, with plenty of light, is crucial for successful growth.
Division Propagation
Propagation through division is a quicker and easier method for Lycopodium obscurum var. isophyllum. One can divide this plant during the spring or summer when the plant is actively growing. Lift the plant carefully and divide it into sections, ensuring that each section has healthy roots and new growth.
After division, ensure that each section is replanted in the soil at the same depth it was previously growing. Water each section thoroughly and place it in a shaded area to reduce stress. You can expect good growth and development from division propagation in the same growing season.
Stem Cuttings Propagation
Propagation through stem cuttings is another viable way to propagate Lycopodium obscurum var. isophyllum. One can take cuttings from the parent plant during the summer months when the plant is actively growing. Choose healthy, mature stems with at least two nodes or leaves on them.
Remove the lower leaves, and dip the cut end of the stem in rooting hormone before placing it in rooting medium. Ensure that each cutting has good contact with the rooting medium, and water it well. Place the cuttings in a warm, bright place, out of direct sunlight, to root. After a few weeks, check for roots, and once the rooting has developed, replant each cutting into its pot and water it thoroughly.
